FLUSHING-TANK.

To all whom it may concern:

Be it known that I, GEORGE I'L-BAILEY, a resident of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Flushing-Tanks, (Case 6,) of which the following is a specification.

This invention relates to flushing tanks, and more particularly to tanks for water closets and the like formed of sheet metal and enameled.

The object of the invention is to provide a tank of the character specified of simple construction, economical to manufacture, sightly in appearance, and which is not open to the objection of sweating.

The invention comprises a tank constructed and finished in the manner hereinafter described.

In the accompanying drawings Figure 1 is a front elevation of my improved tank, the outer tank being partly broken away to expose the inner tank; Fig. 2 is a rear elevation of the same; Fig. 3 is a horizontal section showing one end of the tank; Fig. 4: is a vertical longitudinal section through the tank looking toward the rear; and Fig. 5 is a vertical transverse section through the tank.

My improved tank comprises the inner or water holding tank 1 and the outer tank or jacket 2, which is suitably spaced from the inner tank so as to leave an air space and prevent sweating of the outer tank or jacket.

The mm; or jacket 2 is formed of sheet metal having its front 3 and ends 4 formed from a single sheet of metal bent to shape in any suitable way and preferably with rounded corners and also preferably having the rear vertical edges of the end walls bent inwardly as at 6. The lower edge of the front and end walls is curved outwardly to form the bead 7 and then is preferably turned inwardly horizontally to form flange 8. The top edge of the front and side walls likewise is curved outwardly and then inwardly as shown to form the top strengthening and ornamenting swell or bead 9. The bottom of this jacket is formed from a sheet 10 having its end and front edges welded to the lower edges of the end and front walls of the jacket, preferably by a butt-weld as indicated at 11. The rear edge of the bottom is turned upwardly, as at 12, to form a retaining wall to prevent the dripping of any condensation which may collect between the inner tank and outer acket, this upturned Specification of Letters Patent.

flange being welded at the corners to the inturned flanges 6 on the rear edges of the end walls, the joint being indicated at 14;. A cross connecting member 15 is preferably used at the top of the jacket to connect the end walls thereof, this member being a narrow plate welded to the inturned flanges of the end walls, the weld being formed at 16. This cross connecting member has its upper edge beaded, as at 17, to give the necessary strength and finish. Preferably also an intermediate cross connecting member 18 is welded at 19 to the inturned flanges of the end walls, but this may be dispensed with if desired, and if used may be riveted instead of welded to the flanges of the end walls. The major portion of the back of the outer tank or jacket is open as shown in Fig. 2. The inner or water containing tank 1 is also built up of sheet metal, being formed of two pieces, namely, one piece forming the front wall 19 and end walls 20, and another sheet forming the bottom 21 and rear wall 22. These sheets are united by welding at the rear vertical corners and the bottom end and front corners.

The top edges of the front and rear walls are strengthened by a flange formed by bending the metal outwardly and doubling it back on itself as shown at 23, Fig. 5. The top edge of the rear wall is flanged, beaded or doubled on itself, as at 25, to give strength. The rear wall of the inner tank and the cross connecting member 15 of the jacket or outer tank are provided with registering horizontal slots 26 for receiving screws or other means for connecting and supporting the tank from the wall or other base. In this manner both the outer jacket and inner tank are suspended from the supporting means, so that the weight is taken care of by a double thickness of metal which is of importance as it enables fairly light sheet metal to be used. The slotted connection permits adjustment of the inner tank with relation to the outer tank to get the fittings into alinement.

Both the outer tank or jacket and the inner tank are completely coated both exteriorly and interiorly with a suitable coating of enamel fused on in the usual way and which covers all joints, defects, scratches and the like in the metal, rendering the same sightly and also rendering the same non-oxidizable. The top of the tank is closed by a cover 28 also formed of sheet metal and enameled and having its end and front edges turned downwardly and then inwardly to form the hollow swell or flange 29 which slips over the bead 9 on the top of the outer tank or jacket from the front. The cover may be held in place by means of a pin or bolt 30 extending through the beads on the cover and jacket. The rear edge of the cover has a slight flange 31 formed thereon but not of sufficient depth to interfere with the cover being put in place or removed by sliding the same horizontally from the tank. hen the cover is in place the flange 31 lies behind the ends of bead 9 on the body and prevents the cover being removed without slightly raising its rear edge.

Extending through registering openings in the bottoms of the inner tank and the outer tank or jacket are the flushing outlet fitting 3'3 and the inlet, or ball-cock fitting 34.. Both of these fittings are provided with threaded extensions which receive nuts 36 between the bottoms of the two tanks and additional nuts 37 below the bottom of the outer tank or jacket. Suitable rubber or other packing washers 38 are provided between the fittings and the bottoms of the tanks and between the nuts and the bottoms of the tanks for making water tight connections and preventing injury to the enamel. These washers, however, are thin, and the bulk of the space between the bottoms of the tank is filled by the metal nuts 36 which act as unyielding spacing members. The flushing valve operating rod i0 extends through a bushing ll fitted in a hole through the front wall of the outer tank or jacket and is provided on its outer end with operating handle 4.2.

Both the inner and outer tanks described are formed of a plurality of sheets which are bent to shape and united by welding. No drawing of the metal is necessary but the operation of shaping is a simple bending one, and can be done either in dies or other form of bending apparatus. Consequently sheet metal of suflicient thickness to properly take and hold the enamel can be used. The double construction of the tank due to the air space between practically prevents sweating. It can be manufactured at a reasonable cost.
